Controlling a well injection operation, such as a well fracturing operation, includes identifying a flow characteristic of a fracturing fluid, identifying a flow characteristic of a base fluid used for forming the fracturing fluid, determining an amount of friction reduction change of the fracturing fluid, and adjusting the amount of friction reduction of the fracturing fluid to coincide with a selected friction reduction amount. Identifying a flow characteristic may be performed by a rheology measuring device including a measurement tube, a first pressure sensor disposed at a first position on the measurement tube, a second pressure sensor disposed at a second position on the measurement tube, a flow meter disposed at a third position along the measurement tube, a temperature sensor disposed at a fourth location along the measurement tube, and a control unit interconnected to the first and second pressure sensors, the flow meter, and the temperature sensor.
